Kris, thanks for taking the time to work on this. Like I said in the upstream report I filed over at fd.o (http://bugs.freedesktop.org/show_bug.cgi?id=15096) this issue is not limited to Compiz but 3D apps in general.
I tried your suggestion and I do not have the same problem with the Braid screensaver. I can watch it in the preview just fine for several minutes (although I noticed it does not work properly in fullscreen – no freeze, though). It's not a 3D screensaver anyway, so I guess your problem is not exactly the same. X never recovered here from the freeze also (at least not within an hour, which was the longest time I waited one time). But I tried the Bubble3D screensaver next to it and the X almost instantly froze. Interestingly the backtrace is more verbose this time (attached). ** Attachment added: "backtrace-bubble3d" http://launchpadlibrarian.net/12894430/backtrace-bubble3d -- X freezes in drmCommandWrite() when Compiz is enabled on ATI Radeon Mobility 9600 https://bugs.launchpad.net/bugs/195051 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
